I've had my tv for about 3 months and on the weekend while watching a blu ray i noticed greyish patches in all four corners of the screen when the movie went into dark scenes. I adjusted the backlight level and turned it down to 3 and it reduced the greyness a little but they are still visible and now i can't help but focus on them when i'm watching something. Is this a backlight bleeding issue? can it be fixed or should i be looking at getting it replaced? its a great tv i love the picture it gives but after forking out my hard earned i expected better i'm yet to contact the store where i bought it. anyone else had this problem? is this a common fault with lcd's? any advice would be great thanks
